They may come from out of nowhere, but supplemental updates are a good thing.

On that note, Apple has released its Mac OS X 10.7.3 Supplemental Update. The update, a 38k download (provided you have Mac OS X 10.7.3 already installed), resolves an issue when restoring a Mac from a Time Machine backup.

As usual, the update can be located, snagged and installed via Mac OS X’s Software Update feature. The software requires an Intel-based Mac and Mac OS X 10.7.3 or later to install and run.

If you’ve tried the update and have any feedback to offer, please let us know in the comments.

Per 9to5Mac, C-Spire Wireless is now selling the iPhone 4S for US$50 off the standard retail price. The discount, which is only available when signing up for a new two-year agreement, brings the price for the 16GB iPhone 4S to US$150 and the 32GB and 64GB models to US$250 and US$350, respectively.

In addition, the carrier is offering US$25 off the 8GB iPhone 4, bringing the price for that model to US$75. C-Spire launched the iPhone 4S on its network last November.

Even if you’re one of the largest tech companies on earth, you never quite control when a soon-to-be-launched product’s accessory line arrives.

Per PhoneArena.com, a number of Best Buy stores have reportedly begun to receive cases sealed in boxes for Apple’s third-generation iPad ahead of Wednesday’s anticipated unveiling.

The cases have shipped in boxes with a pink sticker stating “Do not display until official iPad 3 launch,” an anonymous tipster told the site. Cases for the so-called “iPad 3″ are said to be shipping in bulk, as third-party manufacturers are planning for Apple to begin selling its next iPad soon after it is officially announced.

“The shipment is not of just a few cases — there’s over 1,000 Targus Versavu 360 stands for the next-gen iPad shipping to Best Buy, meaning that it won’t be long until the actual tablet hits shelves,” the report said.

Multiple leaked components from Apple’s supply chain have suggested the next iPad will feature an external design largely the same as the current iPad 2. The third-generation iPad is expected to be slightly thicker, with edges more tapered than the iPad 2.

Despite minor tweaks to the design, its expected that Apple’s magnetic Smart Cover will still work with the next iPad. But Apple’s protective accessory only covers the front, flat screen of the iPad, while many third-party cases cover the aluminum back.

The rumor that third-party cases are being delivered to Best Buy is supported by a picture that surfaced last week, showing the retailer’s inventory system listing “iPad 3″ accessories set to be in stock by next Sunday, March 11. The leaked inventory listings included ZAGG’s InvisibleSHIELD.

The next iPad is expected to be unveiled at Apple’s media event this Wednesday at the Yerba Buena Center for the Arts in San Francisco, Calif. The event will kick off at 10 a.m. Pacific, 1 p.m. Eastern.

The iPad 3 is en route…and it’ll probably have a similar design as the iPad 2.

Per MIC Gadget, a new report claiming to have pieced together several components for the third-generation iPad appears to show that Apple has planned few changes to the design of its popular tablet.

The site posted on Sunday hands-on footage with an alleged front glass panel, rear shell and some internal parts to the next-generation iPad, which is expected to be unveiled at an Apple media event later this week.

The report claimed the purported next-gen iPad components debunk highly speculative rumors that Apple will remove the home button from the device. Though some had pointed to Apple’s invitation to this week’s event as evidence of the arrival of an iPad without a home button, others have claimed that the image simply showed an iPad in landscape mode.

Alleged next-gen iPad cases purchased in Shenzhen, China were found to fit the purported “iPad 3″ rear shell, which reportedly has more tapered edges than the iPad 2, perfectly. According to the publication, case manufacturers have already begun shipping thousands of such cases to the U.S. this past week. The third-generation tablet is expected to be slightly thicker than its predecessor.

Though various reports have suggested that Apple will introduce an LTE iPad at its media event on March 7, the publication’s sources assert that the company is not yet ready to enter the LTE market. According to the report, Apple’s decision to hold off on 4G data will result in the release of the third-generation iPad with the same storage options and pricing as the iPad 2. Author Steve Lo further speculated that LTE-compatible Qualcomm chipsets will “most likely” make their way into the fourth-generation iPad.

The third-generation iPad is expected to have a high-definition Retina Display with four times as many pixels as the iPad 2. The device will also likely sport an upgraded processor, though there is some disagreement whether the new chip will be a quad-core or dual-core model.

Sunday’s report also affirmed expectations that Apple will announce an update to its Apple TV set-top box this week. The new device would reportedly feature an A5X processor employing “lower nanometer manufacturing” to run cooler and more energy efficient. Tipsters went on to claim that a new “one more thing” item, codenamed B28, could make an appearance at Wednesday’s event and may have something to do with Apple’s Siri voice assistant.

Inventory of the current-generation Apple TV appears to have dried up for several different resellers even as talk of an imminent update has picked up.
